Problems solved by technology

[0002] At present, most of the ordinary swimming pool composite materials on the market are ordinary polyester fiber mesh, without the water-repellent treatment of the fiber yarn, so that after the finished swimming pool is filled with water, due to the effect of hydrostatic pressure, the water will migrate along the fiber yarn. , or the pretreatment adhesive adopts PU adhesive. Long-term use will cause hydrolysis of the PU adhesive. In both cases, the production process will cause the gradual destruction of the bonding strength between the composite materials. At present, there are certain defects. , and easy to fade, short service life

Embodiment 1

[0021] The specific steps of the production process are:

[0022] (1) Paste pretreatment on the mesh: Use a coating machine to resist wicking type high elongation, low shrinkage, non-absorbent polyester mesh for dipping and coating treatment of PVC paste, anti-wicking mesh can prevent swimming pool compounding When the material holds a large amount of water, due to the static pressure of the water, the wicking phenomenon of the mesh fiber causes water seepage; the advantage of using PVC paste dip coating treatment is the bonding fastness of the swimming pool composite material and avoiding the use of traditional PU Defects in which the adhesive undergoes hydrolytic degradation. The raw material formula of PVC paste adhesive: EPVC 100PHR, K=61 of the EPVC, DOP 80PHR, low toxicity barium zinc stabilizer 2PHR, antifungal agent 0.5PHR, VP adhesion promoter 4PHR, anti-UV additive 0.5PHR And according to the needs of the production process, add an appropriate viscosity reducer.

technical field [0001] The invention belongs to the technical field of chemical materials, and more specifically relates to a production process of swimming pool composite materials. Background technique [0002] At present, most of the ordinary swimming pool composite materials on the market are ordinary polyester fiber mesh, without the water-repellent treatment of the fiber yarn, so that after the finished swimming pool is filled with water, due to the effect of hydrostatic pressure, the water will migrate along the fiber yarn. , or the pretreatment adhesive adopts PU adhesive. Long-term use causes hydrolysis of the PU adhesive. In both cases, the production process will cause the gradual destruction of the bonding strength between the composite materials. At present, there are certain defects. , and it is easy to fade and has a short service life. Contents of the invention [0003] The purpose of the present invention is to provide a swimming pool composite material p...
